A durable hydrophilic composition , comprising:at least one thermoplastic aliphatic polyester;one or more alkyl, alkenyl, aralkyl or alkaryl anionic surfactants having a melting point of less than 200° C.;wherein the surfactant is incorporated into the polyester.2. A durable hydrophilic composition comprising a blend of:at least one thermoplastic aliphatic polyester; andone or more alkyl, alkenyl, aralkyl or alkaryl anionic surfactants;wherein the surfactant is incorporated into the polyester, and wherein the composition remains hydrophilic after more than 10 days at 45° C.3. A durable hydrophilic composition comprising a blend of:at least one thermoplastic aliphatic polyester; andone or more alkyl, alkenyl, aralkyl or alkaryl anionic surfactants;wherein the composition remains hydrophilic after more than 10 days at 45° C.43. The composition of any of , , or , further comprising a surfactant carrier.54. The composition of any of , , , or , wherein the thermoplastic aliphatic polyester is selected from the group consisting of one or more poly(lactic acid) , poly(glycolic acid) , poly(lactic-co-glycolic acid) , polybutylene succinate , polyhydroxybutyrate , polyhydroxyvalerate , blends , and copolymers thereof.64. The composition of , , , or , further comprising a thermoplastic polymer distinct from the thermoplastic aliphatic polyester.7. The composition of any of the preceding claims , wherein the thermoplastic aliphatic polyester is present in an amount greater than 60% by weight of the thermoplastic polymer present in the composition.8. The composition of any one of the preceding claims , wherein the anionic surfactant is selected from the group consisting of one or more alkyl , alkenyl , alkaryl and arakyl sulfonates; alkyl , alkenyl , alkaryl and arakyl sulfates; alkyl , alkenyl , alkaryl and arakyl phosphonates; alkyl , alkenyl , ...
